Compatible with standard multimeters and test leads, this parasitic drain tester utilizes a bypass switch to protect the meter from power surges during the initial connection. Replaceable in-line fuses provide protection for both the meter and tester if a high current source remains active, allowing the equipment to stay connected until vehicle computer systems shut down. The integrated stacking banana connectors facilitate simultaneous voltage measurements at multiple locations to isolate the drain.
